module Ext:sig
..end
This module allows access to volatile references for other groups,
sessions, or client processes.
Use it in conjunction with functions like
Eliom_state.Ext.iter_volatile_sub_states
to get the sessions from a group (or the processes from a session).
val get : ([< `Client_process | `Session | `Session_group ], [< `Data ])
Eliom_state.Ext.state -> 'a Eliom_reference.Volatile.eref -> 'a
get the value of a reference from outside the state.
If the value has not been set yet for this state,
it will raise exception Eref_not_initialized
.
val set : ([< `Client_process | `Session | `Session_group ], [< `Data ])
Eliom_state.Ext.state -> 'a Eliom_reference.Volatile.eref -> 'a -> unit
val modify : ([< `Client_process | `Session | `Session_group ], [< `Data ])
Eliom_state.Ext.state ->
'a Eliom_reference.Volatile.eref -> ('a -> 'a) -> unit
Warning: the function will be executed with the current context
val unset : ([< `Client_process | `Session | `Session_group ], [< `Data ])
Eliom_state.Ext.state -> 'a Eliom_reference.Volatile.eref -> unit
